Grating mill



FIG. 1 is a front elevational view of a grating mill showing my new design, the rear view being a mirror image and, therefore, not shown;

FIG. 2 is a left side elevational view thereof, the right side view being a mirror image except for the opposite side of the handle being shown and, therefore, not shown;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof; and,

FIG. 5 is an exploded front elevational view thereof. 

I claim the ornamental design for grating mill, as shown and described.
